Question

Can someone please help with this question?​

Answer 1

Answer:

when A=45°=>cot A=1

and cot^2 A =1

then cot A + 1/cot A = 1+1= 2

similarly

cot^2 A + 1/cot^2 A =1+1=2

Answer 2

It is the simplest question of the earth...XD

just sqaure on both side,

on sqauring u will get

cot^2A+1/cot^2A +2×cotS×1/cotA=4

cot^2A+1/cot^2A=4-2=2

The way someone had solved the first answer is also right

as we know

tan45=1

so cot45 will also be 1 as reciprocal of 1 is 1

so,

here if take A =1

then

cot45+1/(cot45)=1+1/1=2

so,we can say definitely that A=45

putting this value of A in second we get

cot^45+/(cot^45)=1^2+1/1^2=2

(still waiting for u)
